TL;DR: In this article, the authors employed hydrodistillation for the extraction of essential oil from the leaves of the patchouli plant and found that the quality of the extracted essential oil is dependent on the amount of patchoulol and extraction time.
Abstract: Hydrodistillation has been employed for the extraction of essential oil from the leaves of patchouli plant. The yield of patchouli oil is dependent on solid loading, water volume, size of leaves and extraction time. The optimization of the process parameters has been performed using the Taguchi method while analysis of variance is used to identify the impact of parameters on the yield. The highest yield of patchouli oil (1.53%, w/w) is found at 30 g of solid loading, 900 mL of water volume, 4 mm size of the leaves and 150 min of extraction time. Among the parameters studied, extraction time had a greater impact on the yield of patchouli oil. Amount of patchoulol is maximum (64.9%) in the essential oil obtained under optimized conditions, thus, providing better quality of the essential oil.

TL;DR: A comparative study of patchouli oil using Water-Steam Distillation and Water Bubble Distillation techniques has been studied as mentioned in this paper, which aims to compare two distillation techniques in order to find out the optimal distillation technique to increase the content of Patchouli alcohol (patchoulol).
Abstract: A comparative study of the quality of patchouli oil using Water-Steam Distillation (WSD) and Water Bubble Distillation (WBD) techniques has been studied. The raw materials were Patchouli plants from Samigaluh village, Kulon Progo district, Yogyakarta. This study is aimed to compare two distillation techniques in order to find out the optimal distillation technique to increase the content of patchouli alcohol (patchoulol) and the quality of patchouli oil. Pretreatment such as withering, drying, size reduction and light fermentation were intended to increase the yield. One kilogramm of patchouli was moisturized with 500 mL of aquadest. The light fermentation process was carried out for 20 hours in a dark container. Fermented patchouli was extracted for 6 hours using Water-Steam and Water Bubble Distillation techniques. Physical and chemical properties test of patchouli oil were performed using SNI standard No. SNI-06-2385-2006 and the chemical composition of patchouli oil was analysed by GC-MS. As the resul...
